ROM Manager, CWM & Backing Up / Restoring

I have the latest ROM Manager (5.0.1.5) and the latest CWM (5.8.4.9) installed and am a little confused about backing and restoring. When I used RM/CWM on my old EVO 4G it was very straight forward but doesn't seem to be the case with my new GS3.
When I use RM to backup my current ROM, it seems to be successful but doesn't show up in the list of backups when I go to RM and click on "Manage and Restore Backups". However, if I go into Recovery I can find it by navigating to backup and restore. I'm assuming the problem is that RM automatically backs up to my external SDCard while RM only reads from the internal SDCard. I was able to manually backup to the internal SDCard from Recovery and it shows up in the list in RM but the date & time are all messed up (not to mention I can't rename it in Recovery).
I suppose it's not impossible to use but it seems "messy" to me. How is everyone dealing with this?
---
Also how do you manage the backups via Recovery? I now have 6 backups that I made via RM which ended up in the external SDCard but I can't seem to delete them in Recovery. I'm also not sure where they are when I browse in FTP as there is nothing under the clockworkmod directory.

CWM is fastly becoming old school, do some searching for installing TWRP using goomanager. It is an awesome recovery tool with many, many new features not found in CWM.

Twrp is good for backups and being able to run commands but is definatly missing some features.ROM manager has gone to hell but there is an option in settings for using external storage. Ur backups are in clockworkmod/backups. And you can rename ur backups qhile in cwm recovery w/ this. http://forum.xda-developers.com/showthread.php?t=1646108. And if ur gna use twrp, get it from their site and flash in mobile odin. Goo manager sucks and its interface is confusing. Takes an hour to find **** in there. An accident waiting to happen

Thanks for the recommendation. So far so good.

I see what it is. I was accessing it through the app, FTP Server and that app can only read internal SDcard, where the backups are not located.
Thanks for your help.
I'm now all TWRP'ed up and so far it is nice.

Under "Wipe" in TWRP I see Cache, Dalvik Cache, Factory Reset, System, External Storage, Internal Storage and Format Data.
Normally when I flash a new ROM with CWM I would wipe data, cache & dalvik cache. With TWP, when I click on Format Data, it says this wipes all media, including backups & removes encryption. Is that right? Or do I wipe System, which says "This will wipe your ROM"? Thanks.

how to erase securely the phone memory

Please any help on this...
I install several diferents roms, but I noted when I explore my storage, I find I have this folders:
-Sdcard0
-extSdCard ( this its my external sd card 32 gb )
everything its ok, but in my last installed rom ( MSG& Chubbs ) I noted this, in my Device memory ( Phone Memory ) named "Sdcard0" I have differents files... ok, but inside this folder I have ANOTHER folder called "0" and inside this "0" folder I have another files and a lot of them its the same names files ( alarms, android, aokp, application, autodesk, bell cache. dcim, download, etc etc etc ) ..
I try to reinstall any rom and before install the rom, I wipe cache- Dalvik Cache - Factory reset - and wipe System too...but when my phone start and I begin to work on this I see The Device memory its the same.. I have the Sdcard0 folder and inside I have the same "0" folder with a lot of same folders...
please How to clean this memory to only have one root folder? because I don't know if I erase the "0" folder or move the others folders inside the "0" folder or viceverse... maybe I brick my phone?

If I remember correctly isn't the 0/emulated folder just a symlink and not actually taking up more space? Correct me if I'm wrong but I'm pretty sure that's what I read a while back. If you wipe data just make sure to back your stuff up.

You're not going to brick your phone.
Just backup everything you need to your computer or sdcard. Just wipe everything, but don't wipe system or external storage and you should be fine. The worst case senario if something goes wrong afterwards is to reflash your Rom and gapps, which should be on your sdcard as well before you begin and your phone will be ok.

Where did my files go after flashing?

Hey all,
Was bored and needed to update my phone with a new rom so I did some scouting about and found Beanstalk. Now this rom is awesome but previously I was on CleanRom which is also an awesome rom.
When changing from Clean to Bean I used TWRP and wiped Cache, Dalvik and Factory reset. I never wiped system (I know I should have).
Now after doing so, I lost all data files (images, videos, music, etc). I would like to retrieve those. Upon looking through the root directory, I could not find them.
So, any ideas? I'm stumped but I am not giving up. Storage details says I have 10gb, available 2.5gb+. Now where did the 7gb+ go? Also my 6gb for my system as it is a 16gb N7105.
If more info is needed just ask. List all you need to know. I am gunna do some other things that does not involve wiping the device.

If you open up explorer and check the internal sd. You should be able to see a file labelled "0" check in that folder.

Factory reset doesn't wipes internal memory.
Maybe twrp setting was set to /media(not sure which folder it is) directory for internal memory so it wiped the internal memory too

There's plenty of apps on playstore that can do a full search for internal memory and show the largest files. I think a good one would be Memory Maid.

Hello all
Thanks for the feedback.
So what I have done is flashed a new kernel and recovery which is called Devil. I got this for the dual boot feature and within flashing a rom as I noticed a folder called legacy. This folder contains my previous content. All music folders etc.
So I rebooted went onto a few root explorers and could not find it!
I've enabled root and show hidden files and folders. Went to the root of the phone and checked each folder and all folders within and still cant find it.
Recovery shows: /sdcard/0/legacy - Old
Root explorer: /sdcard - New
Root also has another folder storage, with 4 folders; emulated, sdcard0, sdcard1, usbdisk0.
Emulated has 2 folders; 0 and legacy. Both display the new files.
Sdcard0 shows new files.
Sdcard1 shows microSD(Need more disk space for roms)
Usbdisk0 has no files.
This is a mind game. I think the rom created a new system within the old system files and it can't access out but the recovery can.
I have tried mounting the phone to the Pc via recovery but it won't pick up.

Hello all,
Thanks again for the support!
I resolved the issue. The issue was, AOKP based roms create a new file system for the System. It created it within /sdcard/0/legacy.
When I flashed a Sammy based rom and checked the file manager I was able to see all.
So for all who are coming from Sammy to AOKP, please be careful and back up all SDCard contents, regardless if advised it will not affect Internal storage. This is the first time this has happened since G1 days.

I think so becuase I've recently installed the CM on my device, did a factory reset with the CWM recovery but both the internal and external memory (SD) wheren't touched at all, all the files and folders remains where they was.
So it's normal, right?

Yes mate.. when doing the 3 wipes it doesn't touch internal storage. Its only when you wipe either internal storage or /sdcard.
I had to format my sdcard and wipe all data after I transfered it to the PC. This fixed the file system issue but changing from aokp to sammy will do it again and again. Bit annoying. But hey, its always good doing a clean up.
All i had on my phone were a load of pics and vids by camera and 3 albums. All of this would take no more than 2gb.
Camera was 600mb. So where did 5gb go to? So there is a lot of crap from rom changing, ALOT.

TWRP backup - Can I restore some app data without restoring the whole image?

So here's the thing: I made a TWRP backup of my 16GB nexus before I returned it yesterday (multitouch issues, dead pixels) but see now that people are reporting an OTA update that fixes the multitouch issue. I would rather not restore that backup since it is the JSS15J system, so is there a way I can get the data of at least a few apps and restore them individually somehow?
Thanks!

Titanium Backup can do that.

Ok, can it read the data in the TWRP folder? I have used TB a lot in the past but didn't think it might be able to use the TWRP data.

If it's not compressed (I never do), TiBu can do it perfectly.
In Titanium backup pro in it's menu is the option to 'extract from nandroid backup' .
Did it just last week, so I know the current version works.

Use Nandroid Backup Manager. It's free.
It can restore apps and/or data, SMS messages, Call logs and more from your nandroid backup. It can also decompress the backup if it's compressed.

Of course. TWRP has no advanced backup&restore features because it doesn't need them: you will be prompted before each backup&restore action about the partitions.
For data of just single apps use better Titanium Backup. It can extract them from your nandroid backups

Exactly what I do.

marsmallow 6 will update apps + data from your google account. Not sure it's fully implemented yet but it's supposed to work. I've tried it yesterday with a Mm6.0.1 on nexus 7 2013 and many apps were already configured. Not all of them. Going from MM6 to MM6.0.1 might complicate it so maybe it's better to restore with google and do a little work by yourself, to make sure. I gave up on those restore apps. It also give you the opportunity to do a clean up

You need to ..extract/restore individual data files from nandroid backup?
Restore data to an app when switching between ROMs or OS versions?
Well TWRP IS THE ONLY THING YOU NEED! And a PC of course.
Bless the Devs[emoji7][emoji28]
Forget Nan managers, tar.extractors & the insanely complex Bash terminal commands
1. Go to File manager on TWRP recovery, it can read the system data i.e. data/data/ file (while your other file managers can,only data files on SD or ext.SD)
2.Go to data/data and locate the data folder of the app you wish to extract; will be in the format 'com.app name'
3.Push 'Select folder' tab on the screen; it gives you option to COPY the file
4.Move up & paste the data/data file on your readable memmory: sd/ext.SD
And that's it!! Just connect to the PC & pull the file & there u have: your APP DATA FILE!
I was tired using zip extractors, changing file names & struggling with command prompts; then found this[emoji4]

And believe me, I could repack the data into my new ROM just like that!
Not sure if this messes up with your system but I'm going great so far.
So you Upgraded to a higher OS and find some of your apps to be crashing on your new ROM & have a nandroid of your stock:
You are going to switch data files between stock & custom ROM!
1.Flash the Stock ROM & copy app data from the system files to readable memory, as mentioned above, just add a letter & Rename the copy(which again you can do with TWRP!) so that TWRP may not confuse with the new folder
2.Flash the new ROM, uninstall the app that crashes & install the compatible version from the store
3.Allow storage permission from settings; open the app & perform some action so that a storage directory is created,if not already, in the system storage
4.Boot to TWRP recovery in the new ROM , so now you have the data/data folder of the new app you just installed(which is empty) as well as the data/data folder from your stock ROM on your SD/Ext.SD
5. You know were this is going[emoji16] Delete the data/data folder on your running ROM & MOVE(again with TWRP only!) the one from SD ,after restoring its original name, to the data folder from were you just deleted the other.
6.Wipe Dalvik/caches & reboot
7. Other than receiving a pop up that there may be some trouble with your android system, on startup, everything works just fine for me & the App is fully restored!![emoji7]
Didn't even use a PC!!
Such a tool TWRP is[emoji7][emoji120][emoji120][emoji120]
Forgive me, but try this at your own risk, coz as a newbie Im completely unaware of the consequences

NOOB Q About Memory

Hi All,
Hopefully this should be a very quick question. I'm loading CM onto my phone, and this is the first ROM I've ever used. I've loaded CWM, made a backup, and I'm about ready to go and load CW on. I've noticed though that out of the 5 or so gig the phone comes with for internal memory, about 4gb is used up. Is this just the system and the back up and apps?? It seems quite a lot. Will CM fill this up further? Will I encounter any issues?
I hope thats all clear, but excuse me for being a beginner.
EDIT: This is now even more relevant now CM is flashed. I've just looked in the file viewer, and there's still all the folders etc from the old samsung, and amazonmp3 etc etc. I thought the "wipe data/factory reset" in CWM would have cleared all this.....
Many thanks for looking.

Factory reset only wipes the data partition. For the first time installing a custom ROM, and especially going from stock to cm for the first time, you should wipe the system partition which can be done from cwm.

Hi again.
So I finally got round to trying to get this sorted.... and I'm failing. I've booted into CWM, rerun the "wipe/data factory reset", rerun the "wipe cache" then went into "mounts and storage" and did a format of the system partition, but it still hasn't cleared any of the data.
Am I doing something incorrectly? I didn't want to play around with it too much, in case i bork it all. Any help would be massively appreciated.
Also, I'm a bit concerned about what formatting the system partition will do. Does it just clear the rom already on there, and I can then flash Cyanogenmod back on from my sd card?
Thanks

Formatting system partition wipes the currently installed rom / system apps.
How do you know that it is not wiping the data? If you do a system format and your rom still boots then it isn't working properly.
It could be a problem with the version of recovery (cwm / twrp) that you're using. It can't hurt to update it, which could be the case here.
Good luck. Let me know how it goes.

Thanks for coming back so quickly!
So if you see the attached, this is what I'm looking at. The phone has 5.5gb internal memory, of which, looking at the below, I'm using about 1.5gb, BUT I only have 1gb left to use, and I get warnings about lack of memory.... So there's 3gb being used for.... I don't know.
When I first put cyanogen on, I noticed that the file structure from stock was still there (i.e. all the folder my old apps made). I expected when I put CM on that it would wipe everything, including all of those folders.

You can try an app called es file explorer, it has a feature that fully scans the contents of the internal SD card.
It should show a list of all the folders from the old stock data folders. You can multi select and delete what you want.
Another option which is more efficient, is to make a full backup of all the internal data in your PC. Then fully format the internal SD card via cwm and transfer which contents you need back from the PC such as photos and music. Asides from photos, music and other media items, most of those internal SD contents aren't needed as Android uses these folders for app data etc.
Always make back ups.
Your welcome.

Yeah, I have got ES File explorer. I couldn't find a "scan" but I've gone through all the folder on my device and I can see the following:
/storage - 3.83gb
/mnt - 2.11gb
/sdcard - 893mb
A lot of this seems to be duplicated though.... The stuff on mnt seems to be a shortcut to whats in sdcard, and all that in storage seems to be in the other two. I don't technically think it's all duplicated, but different ways to get to the same stuff, which makes me very nervous about deleting any of it....

Just got a liitle program to give a break down. See attached.
Surely my system data shouldn't be that big?

I recommend you make a full back up in your PC and format the SD card and transfer the contents of your current SD folder back. I've done it before on different devices, I do it on first root / cm install coming from stock because of all the old obsolete data. Apps like clean master won't removing it because it's marked as important for stock users. It shouldn't be a problem.
Note:
Having different links to the data partition is normal. It's purpose is compatibility.

It's possible that's reserved for the system. Mine is similar. You can still use it if you convert user apps into system ones.

It's possible that's reserved for the system. Mine is similar. You can still use it if you convert user apps into system ones.

Just found this: http://forum.xda-developers.com/showthread.php?t=2083107
It's something to do with backups. I'm gonna read through that thread and see if I can find out what I can/can't delete without bricking the phone.
Massively appreciate your time and repsonses on this iKlutz. Just out of interest, did you do a backup when you installed a rom? Have you found that the backup is this big??

Use ES file explorer or other file manager with root explorer capabilities.
Go to /data/media
You should see:
0
clockworkmod
legacy
obb
In clockworkmod folder I've found a backup (2.0GB) that was made by mistake to internal sotrage, since I allways do backup in CWM Recovery to external SD.
Deleted and 2.0GB were gained.

Hmmm. Data/Media is empty.... I might delete the back up from CWM. If the worst happens, I can always flash from the external SD card can't i? Do I "need" that back up of the device when it was stock?

Do not delete.
Copy the folder(s) that you have in the "backup" to the external SD card to the "backup" folder in the "clockworkmod" folder.
Then, you can delete the backup folder located in "data/media/clockworkmod/".
I allways save the backup of the stock ROM's.
To restore in CWM recovery, simply choose "restore from external SD card". And to backup, choose "backup to external SD card", or it will backup to the internal memory.

No.... I don't really know what to do with it.
I've got an s3 mini with Cyanogen and CWM and the system data portion is only 54mb.
I might go into CWM and start deleting things. If I delete the backup I made of my stock phone when I first rooted and added CWM, I can't see too many issues.... I can always flash a stock ROM again can't I?

Yes, using Odin you can flash stock ROM again.
Next time do the backups in CWM to the external SD card!
